DRIVE-CHAIN SPEGIPIGATIGN forming part of Letters Patent No. 321,361,dated June 30, 1885.

Application filed April 24, 1885.

To aZZ whom, it may concern.-

Be it known that I, EDWARD HUBER, a citizen of the United States, and aresident of Marion, in the county of Marion and State of Ohio, haveinvented certain new and useful Improvements in Chains; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of thisSIJG(.ifiC&tIO11,2tl1dill which- Figure 1 is a perspective view of twoof the links of my improved chain and their coupling. Fig. 2 is alongitudinal vertical section of the same, and Fig. 3 is a perspectiveview of the coupling.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of drive chains in which the endbars of two rectangular links are connected by means of a coupling-platebent to form hooks at its ends to engage the end bars, and it consistsin the improved construction and combination of parts of the same, ashereinafter more fully described and claimed.

In the accompanying drawings, the letters A and B indicate tworectangular links having round end bars, 0.

r I) is the couplingplate, which consists of a fiat plate of a widthequal to the width between the side bars of the link and having its endsbent or curved upward and toward each other, so as to form flat hooks FF.

The middle of the inner side of the coupling has a transverse rib, E,which forms seats or bearings G for the end bars of the links.

The hooked ends of the coupling-plate have (No model.)

perforations H, through which bolts I, having heads or nuts J upon theirends, may be inserted, spanning the space between the ends of the hooks,and thus retaining the end bars of the links.

The outer sides of the hooks are recessed or countersunk, as shown at K,at the perforations for the reception of the heads or nuts, so as toprevent the latter from projecting out-- side of the surfaces of thehooked ends.

It will be seen that by using rivets the chain can bemade entirely inone section, or of several sections riveted together, and then fast,-ened with bolts, or it can be made entirely with the bolts, so that anylink can be easily removed and replaced.

I am aware that drive-chains have been made with a coupling-plateprovided with hooked ends over which the end bars of the links arehooked, and having keys for retaining the end bars in their seats, and Ido not wish to claim such construction; but

I claim- In a drivechain, the combination, with the EDWARD HUBER.
